A L T R A I N D U S T R I A L M O T I O N Flexible Couplings
DURA-FLEX METRIC COUPLINGS Patent No. 5,611,732 FEATURES Metric Hardware Designed from the ground up using finite element analysis to maximize flex life. Easy two piece element installation. No need to move the hubs during replacement. One spacer size to handle most different between shaft spacings. Light weight element absorbs shock loading and torsional vibration. Same hubs used on both spacer and standard elements. No lubrication. Good chemical resistance. The specially designed split-in-half element can be easily replaced without moving any connected equipment. Taper-Lock is a registered tradename of Rockwell Automation-Dodge. F2 7

Determine the Load Characteristics and the Service Factor Prime Mover Typical Applications Load Characteristics Class A B C Agitators (pure liquids), Blowers (centrifugal, Can and Bottle Uniform Even loads - no shock - non Filling Machines, Conveyors - uniformly loaded or fed (belt, reversing - infrequent starts (up chain, screw), Fans (centrifugal), Generators (uniform load), to 10 per hour) - low starting 1.0 1.5 2.0 Pumps (centrifugal), Screens (air washing, water), Stokers torques (uniform load), Woodworking Machines (planers, routers, saws) Beaters, Blowers (lobe, vane), Compressors (centrifugal, rotary), Moderate Uneven loads - moderate shock Conveyors - non uniformly loaded or fed (belt, bucket, chain, shock Infrequent reversing-moderate screw), Dredge Pumps, Fans (forced draft, propeller), Kilns, torques 1.5 2.0 2.5 Paper Mills (calendars, converting machines, conveyors, dryers, mixers, winders), Printing Presses, Pumps (gear, rotary), Shredders, Textile Machinery (dryers, dyers) Cranes (bridge, hoist, trolley), Fans (cooling tower), Generators Heavy Uneven loads - heavy shock - (welding), Hammer Mills, Mills (ball, pebble, rolling, tube, shock frequent starts and stops - high tumbling), Pumps (oil well), Wire Drawing Machines starting torques - high inertia peak loads 2.0 2.5 3.0 Note: The above applications depict the generally accepted conditions encountered in industry. Conditions subject to extreme temperatures, abrasive dusts, corrosive liquids, excessively high starting torques, etc., must be considered as extra heavy shock loads. These conditions will increase service factors. Consult TB Wood s for these selections. C. Calculate Design Horsepower or Design Torque If Prime Mover is a 970, 1450, or 3000 rpm motor. Design KW = Prime Mover KW x Service Factor Go to page F2 9 and reference the corresponding motor rpm column. If Prime Mover is not one of the three speeds listed above. Design KW @ 100 rpm = (Primer Mover KW x Service Factor x 100) / Coupling RPM Go to page F2 9 and reference KW @ 100 RPM column. If Using Prime Mover Torque Design Torque = Prime Mover Torque x Service Factor Go to page F2 9 and reference Torque column. F2 8
DURA-FLEX METRIC COUPLING SELECTION (continued) D. DURA-FLEX Couplings are sold by component A DURA-FLEX Assembly consists of one element (STD or Spacer) and two hubs (BTS or QD). Optional high speed rings may also be ordered for spacer elements. Below is an ordering example for Dura-Flex Couplings.
